Description
Background of the Invention
1) Field of the Invention
This invention relates to dish drainers made up of a dish rack and a drain tray, in general, and more particularly, to an apparatus for use in the drain tray to remove liquid accumulated in the dish drain.
2) Description of the Prior Art
Dish drain trays and dish racks are known in the art, see for example, U.S. Pat. Nos. 3,952,875; 4,531,641; and 4,854,537. Typically, wet dishes are placed in a dish rack for air drying after the dishes have been washed with water. A receptacle or drain tray, as it is known in the art, is positioned below the dish rack. The water drips from the plates and accumulates on the drain tray. Generally, the water accumulates in pools for substantial periods of time before it eventually evaporates. This accumulated water can cause several problems, namely, bacteria growth and/or mold growth.
It is an object of my invention to eliminate the accumulation of water in drain trays that remain on the drain tray for a substantial period of time.
Summary of the Invention
My invention is a mat that is adapted to be received in a dish drain tray or similar receptacle that includes a plurality of wicking sections in fluid communication with each other. The wicking sections are made of a wicking material adapted to wick a liquid, such as a fibrous material like cotton. Preferably, at least one of the wicking sections directs the water away from the dish drain toward a sink. Preferably, the mat includes a plurality of longitudinal sections crisscrossing each other. The wicking mat can be disposable and used in combination with a dish rack and drain tray.
Also, my invention is a method for removing a liquid from a receptacle that includes the steps of:
(a) resting a wicking mat on the receptacle;
(b) placing a liquid in the receptacle;
(c) wicking the liquid into the wicking mat;
(d) moving the wicked liquid through the wicking mat toward an exit end of the wicking mat; and
(e) directing the wicked liquid away from the exit end and away from the receptacle.

Description of the Preferred Embodiments
Referring to FIGS. 1-3, a wicking mat 10 is shown, made in accordance with the present invention. The wicking mat 10 is made of a plurality of longitudinally extending strips 12 and are crisscrossed by a plurality of horizontally extending strips 14. The horizontal strips 14 are attached to the longitudinal strips 12, preferably by being sewn together. However, the horizontal strips 14 and vertical strips 12 can be laid on top of each other so that they are in fluid communication with each other. Alternatively, the wicking mat 10 can be cut from a single piece of material so as to define longitudinally extending sections and horizontally extending sections.
The strips 12 and 14 are made of a wicking material, i.e., a material adapted to wick or absorb a liquid. Generally, the wicking material is a fibrous material. Preferably, if the strips 12 and 14 are to be used for absorbing water or wicking water, they should be made of a cotton material, such as Sorbent Rug Blue or Sorbent Rug Black, which is sold by Conwed, Inc. of Delanco, N.J. 08075.
The wicking mat 10 rests on an upper surface of a drain tray or receptacle 18. Typically, the drain tray 18 is made of rubber or a polymeric material. Preferably, the drain tray 18 should be cleaned prior to placing or resting the mat 10 thereon. The drain tray 18 includes a flat section 20 adapted to accumulate water and a plurality of side walls 22. As shown in FIG. 1, a passageway 24 is defined in a wall 22 through which an extending portion 26 of the longitudinal strips 12 passes through. The extending portions 26 have ends 27 that are positioned below the main portion or body portion 29 of the wicking mat 10. The body portion 29 rests on the drain tray flat section 20. The body portion 29 includes all of the horizontal strips 14 and portions of the longitudinal strips 12. Preferably, the ends 27 of the extending portions 26 extend below the drain tray 18.
As shown in FIG. 4, a dish rack 16 is adapted to rest on the drain tray 18 in a manner well known in the art. Alternatively, the dish rack 16 can rest on the mat strips 12 and 14. In either case, the dish rack 16 is positioned above the mat 10 so that wet dishes, glasses, etc. placed in the dish rack 16 to dry are positioned above the mat 10.
In operation, wet dishes and plates are received by the dish rack 16 and any accumulated water on them drips into the drain tray 18. As shown in FIG. 5, water pools 28 accumulate in the drain tray 18. The water pools 28 are then wicked into the strips 12 and 14 and the wicked water moves toward the extending portions 26. Arrows drawn on FIG. 5 illustrate the movement of the wicked water. The wicked water then exits ends 27 in the form of water drops 30. The exiting water is directed into a sink or other receptacle away from the drain tray 18 and mat 10. The mat 10 quickly and inexpensively removes the pools of water that would otherwise accumulate and lay in the drain tray 18. I have found that the ends 27 should be positioned below the upper surface 32 of the flat tray section 20 for the water to quickly drip from ends 27.
After a period of time, the mat 10 will become dirty from food particles. This affects the performance of the mat 10. Therefore, the mat 10 should be disposed of and replaced with a new clean mat. Preferably, the mat 10 is sold as a separate item from the dish rack 16 and drain tray 18; alternatively, they may be sold as a set. The longitudinal strips 12 and horizontal strips 14 may have to be cut to fit in the appropriate sized drain tray 18. The longitudinal strips may also have to be cut so that the ends 27 are positioned in a sink.
The wicking mat 10 can also be used to wick liquids other than water. In that case, an appropriate wicking material should be chosen to effectively wick the liquid, such as for example, a mat 10 made up of polypropylene to wick an oil-based product.
FIGS. 6 and 7 show another wicking mat 50, made in accordance with the present invention. Mat 50 includes a body section 52 and an extending section 54. Mat 50 is similar to mat 10, except mat 50 is in the form of a continuous sheet as opposed to in the form of a plurality of crisscrossed strips. Mat 50 is preferably made from a single piece of wicking material as previously described. The body section 52 is preferably wider than the extending section 54. The body section 52 rests on the drain tray flat section 20 and the extending section 54 extends from the drain tray flat section 20 so that the extending section end 56 extends below the upper surface 32 of the drain tray 18. Preferably, end 56 extends below the drain tray 18. Water dripping onto the body section 52 will be wicked toward the extending section 54 and exits end 56 in the form of drops 30.
FIG. 8 shows a wicking device 70 used to clean up oil spills on water. FIG. 8 shows a plurality of "T" shaped wicking strips 72 made of polypropylene. I have found that wicking strips of fibrous polypropylene will wick oil, but is not as effective in wicking water. The strips include a frame member to permit the strips to maintain their "T" shape. Ends 74 of the strips are received in an open topped receptacle 76. A float ring 78 is provided around an upper edge of the receptacle 76.
The wicking device 70 operates as follows. After an oil spill occurs on water, the wicking device 70 is placed on the spill area. The oil is wicked by strips 72 towards receptacle 76. The float ring 78 is of sufficient buoyancy so that the upper edge of the float ring 78 is positioned above the liquid. The ends 74 are positioned within the receptacle 76 below the remainder of the strips 72 that are soaking up the oil.
The oil then is wicked from the water surface into the receptacle 76 and exits the ends 74 in the form of drops of oil. The accumulated oil 80 in the receptacle 76 can periodically be removed. After the oil is wicked, then the device 70 can be removed from the water.
Having described the presently preferred embodiments of my invention, it is to be understood that it may otherwise be embodied within the scope of the appended claims.
